Abstract

Production of oxidation-stable unsaturated fatty acids (oleics) with an iodine number of 60-130, a cloud point under 11 degrees C, that contain predominantly unsaturated fatty acids, more than 65 wt. % oleic acid and less than 16 wt. % linoleic acid comprises (a) optionally partially hardening natural oils and/or fats; (b) splitting to fatty acids and glycerol; (c) optionally partially hardening the fatty acids; (d) separating the fatty acids into chiefly unsaturated fatty acids (oleics) and chiefly saturated fatty acids; and (e) working up the obtained crude oleics by distillation: provided that at least one partial hardening is carried out in the course of the whole process. An Independent claim is given covering the oxidation-stable products of the process.
